Drag force is a type of force that acts in the opposite direction of an object's motion through a fluid, such as air or water. It is caused by the resistance of the fluid to the object's movement.
The force of gravity is a fundamental force that exists between any two objects with mass. It is the force that pulls objects towards each other and is responsible for keeping planets in orbit around a star.
Drag force and the force of gravity are two separate and distinct forces. Drag force depends on an object's speed and the properties of the fluid it is moving through, while the force of gravity depends on the masses of the two objects and the distance between them.
Drag force becomes significant when an object is moving at high speeds through a fluid, such as when a plane is flying or a car is driving. It can also become significant when an object has a large surface area and is moving through a fluid, such as a parachute or a kite.
The effects of Drag Force can be reduced by making an object more aerodynamic, meaning it is designed to minimize resistance from the fluid it is moving through. This can be achieved by using streamlined shapes and smooth surfaces. Additionally, reducing an object's speed can also decrease the impact of Drag Force.
